FR4 epoxy fiberglass insulation sheet is a high-performance rigid laminate made from woven fiberglass cloth and epoxy resin under heat and pressure. It is widely used in electrical insulation and industrial applications where both mechanical strength and electrical reliability are required.
FR4 is one of the most commonly used glass epoxy insulation materials because it offers a strong balance of electrical insulation, mechanical strength, flame resistance, dimensional stability.
FR4 is an abbreviation for "Flame Retardant 4". It is a specific level of G10 epoxy glass laminate with the addition of flame retardants such as brominated epoxy resin, achieving a stringent flame retardant standard (UL94 V-0). FR4 is designed to self-extinguish rapidly once removed from an open flame, a fundamental safety requirement for electronic products to prevent fires caused by circuit failures.
Selecting 100% pure fresh beer yeast mud, obtain with roller drying which rich in 18 types of amino acids, vitamin B, organic microelement and minerals. Brewer's yeast powder is a natural plant protein source,the pure protein and carbohydrates, can reduce the usage amount of blood powder.
R5 laminated insulation sheet is a flame-retardant epoxy fiberglass laminate used in electrical insulation and structural applications where high mechanical strength, dimensional stability and reliable heat resistance are required.
It is made from epoxy resin reinforced with woven glass fiber cloth under heat and pressure. Compared with standard glass epoxy laminates, FR5 is commonly selected for applications that require better thermal performance and flame retardancy while maintaining strong electrical and mechanical properties.
For buyers who need a rigid laminate that can handle both insulation duty and machined structural use, FR5 is a practical and widely accepted material choice.
Chengrui Insulation supplies FR5 laminated insulation sheets for electrical equipment manufacturers, transformer factories, new energy equipment producers, industrial processors and insulation parts distributors. We can supply FR5 sheets in standard panel sizes or custom-cut sizes, and we also support CNC machining, drilling, milling and part fabrication based on customer drawings.
